MACHINE FOR MAKING WOODEN RINGS.

SPECIFICATION forming part of Letters Patent No. 273,806, dated March13, 1883.

Application iiled January 12, 1883. (No model.)

To all whom it may concer/ii:

Be it known that I, REED V. Boron, ot' Toledo, in the county of Lucasand bta-te of Ohio, have invented an Improved Machine for Making \VoodenCurtain-Rings, of which the following is a specitication, referencebeing had to the accompanying drawings, in which- Figure l is a frontelevation, partly in sec- Fig. 2 is a side elevation, partly in section.Fig. 3 is a top view of the table partly broken away. Figs. et, 5, 6,and 7 are ditt'erent views ot' the cutter-head, showing' its variousparts. Fig. 8 shows a blank board or strip bored and ready for theoperation ot' the inachine. Fig. 9 shows the saine after having passedthrough the machine. Fig. l0 is a cross-section through the blank afterhaving been cut oii one side, and Fig. 1I shows the saine at'ter havingbeen cut on both sides.

The main object of my improved machine is to rapidly and economicallycut curtain-rings, with as little waste as may be, from suitable stripsof board.

Referring to the letters upon the drawings, A indicates a suitable mainframe, to the back part of which are sei-tired two posts, B, or otherequivalent means for supporting the bearings ot' a vertical arbor, O,provided with a bandpulley, D, or other suitable means for revolving it,and carrying at its lower end a detachable cutter-head, E.

Fitting within the main frame is a verticallyreciprocating frame, F,carrying a table, G, and capable of being suitably elevated by means ot'an ordinary foot-lever, H.

I provide anti-friction wheels I within the sides ot the main frame,grooved in their peripheries, and also provide the sides ot' thereciprocating frame with guideways or tracks K, fitting in the groovesof the anti-friction wheels and constituting the bearing-surfaces of thereciprocating frame, whereby friction is reduced to a minimum and thereciprocating traine is guided accurately in its movements.

The table is provided with a small hole, L, concentric with the axis ot'the arbor C, and with two parallel guideways, M. These guideways may besecured with screws or otherwise to the top of the table, so that theycan be shitted laterally to bring them closer together or fariher apart,according to the size ot' rings desired to be out.

The cutter-head E is attached to the arbor C in any suitable manner soas to be readily detachable, but preferably, as illustrated in thedrawings, by means ofa shank fitting within a socket in the arborconcentric with its axis. The lower end of the cutter-head isdish-shaped or cup-shaped, and provided with one or more inclined seats,N, to which one or more cutters, O, are secured by means of setscrews I.These cutters preferably straddlc the set-screws, as shown, and areadjustable up and down to regulate the depth of cut. Their cutting-edgesare ot' course semicircular when they are designed for cuttingcurtainrings; but when designed for cutting circular grooves of any`kind or rings having small circular grooves or projections theircutting-edges may be varied accordingly. The bottom ot the cutter-headis provided with a semiciicular groove, Q, or with any otherconformation, to correspond with the outlines of the cuttingedges of'the cutters. The result will be that the cutting-edges will project atall points equally below the bottom of the cutter-head and operate asthe blade of a plane operates with reference to the bottom of the plane,and the thickness ofthe shaving cut may be regulated by setting thecutters up or down as the blade of a plane is set by a carpenter. Thecutter-head is also provided with a shoulder or stop, x, to limit thedepth of cut, which it does by bearing against the stock outside of thecutters whenever a cut sufficiently deepis made.

Projecting from the center of the cup of the cutter-head is a pin, R,provided with a coiled spring, S, the pin being preferably pointed 0rconical at its lower end.

The blank shown in Fig. S is provided with holes T, of a size to admitthe pin R, and ofthe proper distance apart to permit the rings to be cutwithout waste of the stock. Such a blank is placed upon the tablebetween the guideways M, its tirst hole being about coincident with thehole L in the table, which will bring it substantially in line with theaxis ol' the center-pin R. 4

The cutters being properly adjusted and the cutter-head being in rapidrevolution through power applied to the arbor O, the operator places hisfoot upon the foot-lever H and raises the reciprocating frame and table,carrying up ICU 1o hole through. the stock.

2 yerases the stock, and the center-pin passes through y the rst hole T,and the cutters rapidly do 5 ragainst the cutters until the limit oftheir cut is reached. rllhe pressure of the foot is ,then withdrawn, andthe table carrying the stock drops down out otl reach of thecutter-head, the coil-spring S aiding to release the pin from the Theblank is then slid forward until the next hole T is in position. Anothercutting operation is then performed,and so on t0 the end ofthe blank.The blank is then turned over and cut upon the opposite side in the samemanner, the

depth ot' cuts being such as to substantially sever the rings from theboard. The conical point ot the center-pin serves to facilitate thecentering ofthe stock, because as the stock is zo raised up the pinwedges or pushes it slightly endwise, as may be necessary to exactlycenter it.

I do not in this application claim the cutter head herein described, buthave reserved it for z5 patent in a separate application.

Having thus` described my invention, wh at I claim to be new, and desireto secure by Letters Patent ot' the United States,lis as follows, towit: A

1. The combination of the main frame A, the vertical1yr-reciprocatingframe F, the foot-lever H, the horizontal table provided with theparallel guideways M, the vertical arbor U, and the detachablecup-shaped cutter-head E, provided with av center-pin, R, these partsbeing constructed, organized, and operating together substantially asand for the purposes set t'Orth.'

2. The combination ofthe main frame A, the vertically-reciprocatingtraine F, the foot-lever H, the grooved an ti-fricticn wheels I, andguideways K, the horizontal table provided with the parallel guidewaysM, the vertical arbor C, and the detachable cup-shaped cutter-head E,provided With a center-pin, R, these parts heilig constructed,organized, and ope-rating together substantially as and for the purposesset forth.

In testimony whereof I have hereunto sub-- scribed my name.
